@Harvy66:
Lagging is a result of bufferbloat. While trying to figure out how figure out what ports common game servers use, enabled Codel Active Queue on your firewall queue.
I thank you for your reply, but, honestly, what will 'Codel Active Queue' do with my problem?
as for an example, I have an online Game "XYZ", but they don't provide game port(s) as they are paranoid that it will attract/invite DDOS :(. I have pfSense traffic rules configured, lets say people are playing DOTA 2, League of Legends or Heroes of Newerth while doing streaming/browsing on my LAN and the ping rates are 'acceptable' because of the traffic rules I have created and these Games provide either directly or indirectly with the correct port(s) to configure.
If Game XYZ port(s) are not determined, it will ultimately goes to the default queue (unless otherwise they use same/similar port(s) of other game servers), of which I have configured with less bandwidth.
Once again, I am really sorry as I don't get the whole picture enabling "Codel Active Queue" for this.
